CGI Construction in San Diego, CA | Mason Remodeling Co San Diego
Mason Remodeling Co San Diego provides independent CGI window, door, and construction service across San Diego County. We rebuild and retrofit CGI impact windows daily, and the one thing that makes our CGI work here different is that we build for seismic anchoring and salt-air corrosion, not just the manufacturer spec. If your CGI windows are fogged, seized, or leaking in a San Diego hillside or coastal home, call (619) 673-9302 for a straight answer and a written quote.
Why San Diego Residents Choose Us for CGI Service

We’re an independent CGI service provider, which means we’re not tied to a manufacturer’s script. We diagnose what’s actually failing in your windows and doors, then recommend the fix that makes sense for San Diego, not the one that protects a brand’s warranty terms. Isaac Pruett, our owner, grew up in Los Angeles and picked up a framing hammer before he ever opened a textbook, then turned that instinct into a real skill set at Los Angeles Trade-Technical College. Since then, he and our crews have worked all over San Diego County, from kitchens near Balboa Park to our Bathroom Remodeling in San Diego in neighborhoods where the homes are older than most of our tools.
We source genuine CGI replacement sashes, hardware, and weatherstripping when storm-rating compliance matters, but for non-critical seals and operator parts, we often use aftermarket equivalents that hold up better against San Diego’s salt air. Every crew member who comes to your door is background-checked, identity-verified, and arrives in a clean uniform with a photo ID badge. You’ll get the technician’s name and photo before the visit through our Threshold Standard process, and a written price before any work starts. That’s not a promotion; it’s how we run every job.

Common CGI Construction Problems We Solve in San Diego
- Fogging or seal failure between panes in impact glass. In beach-adjacent neighborhoods like La Jolla and Ocean Beach, years of direct coastal sun and salt spray degrade the insulating seal in CGI impact glass. Once the seal goes, moisture gets in and the window fogs permanently. We replace the failed sash with genuine CGI glass when the original impact rating needs to stay intact.
- Corrosion on aluminum frames and hardware. Salt air from the Pacific accelerates corrosion on CGI aluminum frames, hinges, and locking hardware. In Clairemont and Allied Gardens, where homes sit close to the coast and see consistent marine layer, casement and sliding windows often become stiff or impossible to operate. We strip or replace corroded hardware and refit frames as needed.
- Hillside settlement or minor seismic shifts binding doors and windows. Canyon-rim properties in San Diego shift subtly over time, and that movement binds CGI doors and windows. You’ll see misalignment, air leaks, and water intrusion at the sills. We check the rough opening, adjust or re-shim the unit, and repair any structural framing that has moved.
- Degraded gaskets and weatherstripping from dry heat and UV. Inland San Diego’s dry heat and intense sun bake the original gaskets and weatherstripping on CGI units, especially in original 1950s-60s stucco homes near Mission Valley. Degraded seals reduce the original impact rating and let wind-driven rain through during winter storms. We replace them with materials that tolerate both UV and temperature swings.
- Rotted framing hidden behind stucco exteriors. San Diego’s stucco-over-wood construction hides wood rot for years. Decades of fog drip and occasional rain intrusion rot the rough opening around CGI windows. By the time the window sticks or leaks, the framing underneath often needs rebuilding, which is a structural repair, not a parts swap.
CGI Service in San Diego: What Local Conditions Mean for Your Equipment
San Diego lies in Seismic Design Category D, and that designation changes how CGI windows and doors need to be set into stucco walls. Many hillside and canyon-rim homes with CGI impact windows require additional structural anchoring and sill flashing beyond the manufacturer’s specs to meet the stricter 2022 California Building Code. Crews in Orange or Riverside counties don’t face this in the same way because their seismic categories differ. For us, it means every CGI frame we set into a San Diego hillside wall gets checked for anchor spacing, strap requirements, and flashing details that the original installation may have skipped. We don’t just slide a new window into the old hole and call it done. On a 1958 rancher in Allied Gardens, our tech pulled a pair of CGI Sentinel casement windows that had seized shut from corroded hinge tracks and found rotted framing behind them, the result of decades of fog drip and wind-driven rain. We rebuilt the rough opening, replaced the rotten studs, reset the CGI units with new stainless steel hinges and a full perimeter of flexible flashing, then re-stuccoed to match the original texture. We pulled a permit for the structural repair so the impact rating stays intact, and the owner can now open every window without a fight.
CGI Models & Products We Service in San Diego
We work on the CGI lines most common in San Diego homes: the Sentinel Series impact windows, the Estate Collection windows and doors, the Targa Series impact doors, and the older Classic Series aluminum windows found in mid-century homes across Clairemont, Allied Gardens, and Mission Valley. Our CGI sales & service team keeps commonly needed hardware and weatherstripping locally so San Diego turnaround doesn’t drag. When a job demands exact storm-rating compliance, we use genuine CGI replacement sashes and parts. When the failure is a non-critical seal or operator component, we often reach for aftermarket equivalents with better corrosion resistance for coastal air. If a CGI frame is badly corroded or out of square beyond adjustment, we’ll tell you plainly when replacement costs less than repeated repairs.

AfterCGI Service Pricing in San Diego

Two services drive most of our CGI-related work in San Diego: full impact window installation and standard window replacement. Here’s how those break down in this market:
| Service | Typical San Diego Price Range |
|---|---|
| Impact Window Installation | $9,440 – $29,500 |
| Window Replacement | $5,310 – $17,700 |
What pushes a CGI job toward the higher end in San Diego is structural framing repair behind stucco, seismic anchoring upgrades, or full-frame replacement with permit and inspection. A simple sash swap costs far less. Our estimates are written and line-itemed before any work starts, and they include the permit when one is required. We never start a job without a complete written price. See our San Diego service area page for neighborhoods we cover. For an exact number on your CGI project, call (619) 673-9302.

FAQs – CGI Construction in San Diego
Yes, in most cases. San Diego treats impact window replacement as part of the building envelope, and because many homes sit in Seismic Design Category D, the city requires the installation to meet current anchoring and flashing standards. A direct sash-for-sash swap may be exempt in some situations, but any time the frame comes out or the rough opening is touched, a permit is generally required. We handle the permit for you. Call (619) 673-9302 and we’ll tell you what your specific project triggers.
Fogging between the panes means the insulating glass seal has failed. In Clairemont, the combination of coastal sun, salt spray, and marine layer moisture stresses CGI seals faster than inland locations. Once moisture gets inside the glass unit, the only real fix is replacing the failed sash or the insulated glass unit itself, not just cleaning it. We use genuine CGI glass when the impact rating needs to stay certified. Call us at (619) 673-9302 for a quote on sash replacement.
Yes, and that’s one of the most common setups in San Diego. Hillside homes with slab-on-grade foundations and stucco exteriors need careful shimming and anchoring because the walls move slightly with the slope. We inspect the rough opening, correct any framing that’s out of square, add the seismic anchoring the 2022 California Building Code requires, and flash the sill so water doesn’t track inside. The stucco patching is matched to the original texture, not just smoothed over.
Usually, yes. CGI door hinges, rollers, and locking hardware are replaceable components. In Ocean Beach and other beach-adjacent areas, we swap corroded hardware for stainless steel equivalents that withstand salt air far longer than the original zinc or aluminum parts. If the frame itself is corroded through or the door is out of alignment from repeated swelling and settlement, we’ll show you what’s salvageable and what isn’t before any work starts. Call (619) 673-9302 for a free estimate.
For a standard full-frame replacement, most San Diego homes pay between $5,310 and $17,700, with impact-rated units starting at the higher end of that range depending on size, opening condition, and whether structural repair is needed. A sash-only replacement runs lower. We give a written line-item price before any work starts, so the number you approve is the number you pay. Call (619) 673-9302 for an exact quote, and the estimate is free.
